Not only is this felted backpack perfect for carrying everything from books to a knitting project to your lunch, its fun to make! The main bag is knitted in one piece; the inside and outside pockets, short carrier handle, and adjustable backpack straps are all worked separately, then sewn in place. A spin through the washer felts the softly spun lopi yarn into a dense fabric that wont allow small items or a pencil end to work their way through the surface. Add a favorite funky button to secure the flap and voila! instant favorite.
